The DfT has said that in order to be eligible for the £5,000 grant, cars must meet appropriate safety standards and must have been crash tested. They must also meet minimum range and performance criteria
 
RoadSafe director Adrian Walsh said: 'It is quite right that plug-ins meet the same safety criteria as other cars. We fully support this government initiative, which encourages so much innovation, led by the auto industry, to create safer, greener cars.'
